The sum of two numbers is 12. The first number, x, is twice the second number, y. Which system of equations could be used to find the two numbers? A system of equations. x plus y equals 12. x equals 2 plus y. A system of equations. x plus y equals 12. x equals 2 y. A system of equations. x y equals 12. x equals 2 plus y. A system of equations. x y equals 12. x equals 2 y.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
